I followed all the steps and both my intake check valve and my hose check valve were both good. But when I would plug the hole on the valve cover nothing would happen. When I pull the dipstick out you can hear the hissing sound like there is a leak somewhere. Just curious if I should replace the valve cover and see or take a different route?

I was thinking it was my valve cover so I replaced it. Did not fix the hissing issue coming from the crankcase. The original check valve in the intake is there but was wondering if there is a way to throughly clean it in case it is plugged without pulling the intake.

Nope, get a fix kit from cruzekits.com or replace the intake manifold. Pulling the intake doesn't matter, you can only clean one side of it.

I got a kit from Cruzekit.com and put it in but it seems like it does not want to keep up to speed. If I set the cruise at 70 in 6th gear it stays at like 66-67 unless going down a hill then it will catch back up to 70 until I go up another hill. Was wondering what I should maybe look into next if there is something else that is a common deal on these cars?
